Fn keys on Dell Latitude E6440

Hello,

on my notebook dell-wmi kernel driver generates some scan codes 
when I press some of Fn key combinations. Now all these scan 
codes are mapped to key "prog3". I would like to add some actions 
for these Fn key combinations, so what do you think? Which key 
codes should be assigned for these scan codes? Note that these 
combinations are not special (and labeled) as other (like Fn+F11 
= play/pause) and seems like windows does not recognize them.

Matthew, you are author of dell-wmi driver, do you know if there 
are some other secrets key combinations? And why first 10 Fn key 
combinations generate scan codes?
